We even do things like interfacing the X8 directly to the RS-232 inputs of Exstreamer and Annuncicom for volume control, channel selection etc !

In general, the X8 can be seen as a quite universal, low cost, 5V I/O interface for automation purposes. With its support for Modbus/RTU, Wiegand readers, Dallas Onewire temp sensors, it is suitable for many applications in the automation and data collection area.

Oops – for those who don’t know what a wiegand interface is … nowadays, the “de facto” standard interface for access control readers, keypads etc. Originally a wiegand reader was a specific card reader, able to decode cards which contained a wire pattern, based on the “wiegand” effect. Wikipedia has more, here is the link to the term Wiegand Interface.

If anyone is interested in these special functions, please let me know !
